To a whom it may concern:

Be it known that I,- ALLEN 0. HANEY, a citizen of the United States, residing at Shakespeare, in the county of Kosciusko and State of Indiana, have invented new and usel Improvements in Air and Gas Engines, of which the following is a specification.

y invention relates to improvements in what is known as air and gas engines.

Said invention has for its object to greatly simplify the structure and its operation, accor ingly economizing cost of manufacture and expense of running the same, While certain other advantages are secured thereby as will be made apparent later; and to these ends said invention consists of the combina tion and arrangement of parts substantially as hereinafter more fully disclosed and particularly pointed out by the claim.

the accompanying drawings, the preferred embodiment of my invention, Figure 1 is a vertical longitudinal section thereof. Fig. 2 is a plan view, and Fig. 3 is a side elevation of the same.

In the carrying out of my invention I mount upon a suitable support or base 1a cylinder 2 and a fly or balance wheel equipped crank-shaft 3, in practice adapted to be coupled or connected with the machinery or object to be actuated, the balance or fly Wheel being designated as 3 Within said cylinder are arranged two pistons 4 4, to reciprocate longitudinally therein, one having plvotally connected thereto a single pitman 5, in turn correspondingly connected to the central crank 3 of the crank-shaft 3. The other thereto one end of a rod 6, suitably fitted to be moved and guided through an opening in one end or head of the cylinder 2 and extending beyond the same the requisite distance. Said piston-rod has its outer ,end suitably connected to a cross-bar 7 about centrally of the latter, said cross-bar ha suitably connected thereto near its ends the outer ends of duplicate pitmen 7, whose inner ends are connected to the lateral cranks 3 of the crank-shaft 3, said cranks extending in nearly a diametrically opposite direction from that of the aforesaid crank 3, the; pu xl'ppse oif which is obvious.

e cylinder 2 has in its headed end an air andgasoline mixture containing chamber 9,

having a delivering valved port 10 comniuni cating via the port 11 with theexplosion or iston chambenzf of the cylinder 2. fiaid illustrating piston has fixed being necessary to only state that cylinder has near its opposite or open end an exhaust-port 12 also communicating with its chamber 2*. Said pistons 4 4* are of What I term cup shape, one depth in-its effective surface or area of about an inch and a half, and the other pistona depth in its correspondi surface or area of about two and a half inc es, whereby when said pistons have reached the end of their maximum inward strokes, at which time they are only an interval of about an inch apart, (the adjustment of their strokes being predetermined with that end in view,) a chamber, asit Were, will be thus formed Within the cylinder-chamber of considerably reduced crosssectional area or diameter. Therefore the gasolene and air charge initiallyreceivcd into the cylinder-chamber will, as the pistons are performing their inward or approaching strokes, be taken in between said pistons into their cup-aha ed or sunken eilective surfaces or areas, fina y forming, as above noted, the contracted inner chamber. Thus said air and gasolene charge is subjected to a hi h state or degree of compression in a relative y reduced area and at a much more rapid rate than has otherwise heretofore been ossible Without reducing crosesectionally t e bore or chamber of the piston cylinder itself, which would result in proportionately reducing the air and gasolene charge, andaccordingly the working capacity of the engine. It is also noted that the air and gasolene is driven into the explosion or ignition chamber of the cylinder by the outward stroke of one piston, While the oppositel movi provides simultaneously for the relatively increased expansion action of the asolene and air char e when ignited or explo ed.

A prelighting or priming valved port 13, arranged in the cylinder 2 in its upper portion and communicating with its chamber, is designed, as intimated, for effecting therethrough by the employment of suitable means the initial igniting of the gasolene and air charge. The valve arranged in said port may be of any approved or other form, as a common jump-spark plug.

' The operation of my engine, it is thought, is apparent from the foregoing, it probably the pistons t a having been initially put into motion manually, as Well understood, the air and gasolene charge is admitted via the port 1 i as one piston 4 reaches a certain point in its forward stro enerally lia a piston a into the cylinder charobcr 2 latter reaches the maximum of its said stroke rear of said piston. As said piston makes its return movement or stroke when the other iston 4" of course will make its correspondmg stroke, said charge will be duly compressed by the aforesaid piston, and as the ward or approaching strokes, allowing charging of the cylinder-chamber, which aforesaid. operation of parts, together with the rechargin of the cylinder-chamber, will be as long as the sup l y of the miX-' continue. ture of air and gasol'ene orfue is maintained, It is'also noted that no comas is obvious. plication of valves,

present in my e anced motlon is o it will uncover the port 11, permitting the. passage of said charge in between the two pistons. As the latter make their reverse or approaching strokes it is obvious that said c arge will be further com ressed thereby, also, as before specially noted, be taken in between said pistons and finally be wholly substantially encompassed within a contracted subchamber formed by said pistons at their nearest point or interval of approach; The char e will by this action, it is apparent, be doub y compressed, as it were, in a relatively contracted compass w'ithintbe same cylinder 'ine, while a perfectly baltained thereby in addition exploding and in never to miss fire.

Latitude isallow'ed as to details herein, as they may be changed as circumstancessugest without departing from the spirit of my invention;

I Clairn- I An air and gas engine, em der having an inner piston c into the intake end of said cylinder, and oppositely-moving pistons, said piston-chamber aving a single inlet-port also communicating with said cylinder in'take end and delivering the gas and air charge, after initial compression, to the opposing action of the istons, said inlet-port also adapted to be s ut oii by one of said pistons in its forward or compressing movement, and said piston-cylinder also having a single exhaustport adapted to be uncovered by the opposite piston, in its rearward movement, after the exploding of said charge, substantially as set forth.

In testimony whereof I afliir my signature in presence of two subscribing witnesses.

practice has been found initially by the ap roaching action of the pistons and ultimately by the separatecongea tive action of the interior lesser areas or surfaces of the pistons, whereby it is found in actual practice by me that the friction or impingement produced thereby is effective for the ignition and consequent ex losion of said charge, and that without the a1d of an additional means as usually employed for t e purpose and which is so common that no further elaboration thereof is necessary herein. lhe exploding action of the air and 'gasolene charge w1ll of course have the effect to drive the pistons back to their initial positions, t us effecting their return strokes, conse quently permitting the exhausting of the burned charge via the port 12, and by the momentum thus given the various parts,-including the fiy or balance wheel 3*, said pistons will be caused to also again repeat their forloying a cylin- Witnesses:
